This discourse goes beyond the anachronistic references indicated by these icons and calls into question our entire system of interface metaphors. At one point in time imagining the information stored on your computer as a system of "files" and "folders" was pivotal in transitioning a society from the physical world to the digital one. Now that the transition is largely complete and many people are coming of age who have never known a world without computers, its time to move beyond anachronistic metaphors. We must discover new means of interaction that take advantage of the unique features of the digital medium.
CS Lewis said that ""All language about things other than physical objects is necessarily metaphorical." I can't find the examples he gave, but from your sentence: we must "discover new means of interaction that take advantage..."
"Discover" is made of "dis-cover", meaning "remove the things covering the other thing." The "inter" in "interaction" implies movement between objects in a physical space. To "take advantage" evokes physically grasping something.
Perhaps this is more philosophical than you wanted, but I doubt we'll be leaving behind physical metaphors anytime soon.
I would like to hear an "explain it to me like I'm five" that explained what computer "files" and "folders" are and how they work without using the words or their associated metaphors.
I agree some of the actual system specific icons and metaphors are outdated and junk, but I guess I'm in the camp that thinks these basic metaphors are actually useful in the education of computer interface / mechanisms.
>Now that the transition is largely complete and many people are coming of age who have never known a world without computers, its time to move beyond anachronistic metaphors.
They might have been metaphors once, now they are idioms.
The people who "have never known a world without computers" have also never known a world where there weren't filesystem folders and files.
